听力原文： Hello, everyone. I'm glad to be given a chance to tell you a story. Now I'll begin. Once there lived a lion in a forest. Every day he went about to look for food. The small animals in the forest were all afraid of him. Not far from the forest there were four bulls. They were good friends, and often went about together. The lion tried many times to catch them, but could not do so. Every time he came near, the four bulls stood together to fight him, so he could do nothing to them. One day, the bulls had a quarrel. After that each went his own way. When the lion saw this, he was happy. Then he caught one bull and ate him up. Then he caught another. One by one he caught all the four bulls and ate them up. That's all. Thank you. Where was the lion living?
